Door Sales & Installations (DSI)

What Door Sales & Installations (DSI) does

Door Sales & Installations (DSI) is a B2B supplier of residential door and trim packages to home builders in the Phoenix and Tucson, Arizona metropolitan areas. The company serves 24 builders and packages doors and trim for over 7,000 homes annually, combining product supply, on-site delivery, and professional installation into a single-source solution. Its core product portfolio spans six categories: exterior doors (fiberglass, ENERGY STAR and NFRC3 certified), interior doors, trim and millwork, hardware, shutters, and shelving. DSI positions itself as a higher-efficiency, lower-waste alternative to traditional multi-vendor procurement, with packages delivered on schedule to jobsites and installed by trained in-house teams.

DSI's core technology is operational rather than software-based: refined manufacturing and logistics processes that minimize waste and maximize productivity, enabling it to run a 7,000+-home annual throughput with a lean ~15-person direct headcount supplemented by subcontracted installation labor. The company is a subsidiary of Erickson Companies, which operates within the Synergos Companies family of integrated residential construction services (framing, electrical, HVAC, plumbing, concrete, etc.). DSI maintains direct strategic supplier relationships with branded manufacturers including Woodgrain, ThermaTru, Kwikset, Metrie, Hager, Combo Aluminum, OrePac, Cal Royal, Dividers, and Haley, allowing it to bundle leading products into a specification-driven package.

DSI's revenue model is a one-time product-plus-installation sale per home under B2B contracts with residential home builders, spanning small custom builders to large production developers. Pricing is not publicly disclosed and is likely negotiated on a per-project or ongoing-contract basis. The company is privately held with no funding rounds, no public listing, and no app or software products. Go-to-market is direct sales to builders, supported by a bilingual (English/Spanish) website and limited social media presence (Instagram, LinkedIn). Geographic expansion is led by a dedicated General Manager of Expansion role, with the Tucson market established since 2014 and ongoing focus on growing DSI's regional footprint.
